STEREOSCOPE Filed Aug. 22, 1954 INVENTOR 13w Paar/MIC J '1 /n/a AT'ZRNEp Patented Oct. .29, 1935 UNITED STATES PATENT OFFICE 1Claim.

This invention relates to improvements in stereoscopes, and it is the principal object of my invention to provide a stereoscope of simple and inexpensive construction which can be folded into a comparatively small compass to be conveniently carried in a hand bag, pocket or the like.

Another object of my invention is the provision of a foldable stereoscope the eye-pieces of which are held in a novel and improved manner in the foldable front wall of the instrument.

A further object of my invention is the provision of a stereoscope the rear and front walls of which are held or supported in a wire frame upon which they can be readily folded when not in use.

A still further object of my invention is the provision of a foldable stereoscope the rear wall of which is suited for the support of the exchangeable pictures.

These and other objects and advantages of my invention will become more fully known as the description thereof proceeds and will then be specifically defined in the appended claim.

In the accompanying drawing forming a material part of this disclosure:

Fig. 1 is a perspective view of a stereoscope constructed according to my invention.

Fig. 2 is a section on line 2-2 of Figure 1.

Fig. 3 is a top plan view of the stereoscope.

Fig. 4 is an end view thereof, folded.

As illustrated the stereoscope constructed according to my invention consists of a wire frame consisting of a pair of side bars III, II, the rear ends of which are connected by a bar l2, while the front ends of bars l0, II are angularly bent, as at l3 and I4.

A rear plate I5 is equipped with loops or eyes I, ll through which the rear bar I2 is loosely but frictionally guided so that the plate may be conveniently folded upon the frame.

The angularly bent front ends I3, ll of bars II, II are frictionally guided through loops or. eyes ll, l9 formed in the material of the front plate 20 so as to allow a folding of the plate upon the frame.

The eye pieces or glasses 2|, 22 are held in frames or holders 22, 24 introduced through suitable openings in the plate 20 extending therethrough and having at the front ring flanges engaging the front face of plate 20 to hold the eye-pieces in place, while open or split rings 25,

26 clamp the lenses 2|, 22 in place within their holders. 6 The material of the end edges of plate I! is bent upon itself to provide guide fianges 2l, 2B for the picture cards 29 or the like made in the usual two sectional form so that the rays coming from the picture strike the eyes as if coming direct from an intermediate point, where'the two pictures are seen apparently as one.

' In use plates 20, are set up as illustrated in Figure 1 while they may, when not in use, be suitably folded upon the frame to be convenientl5 ly carried on the person, or in hand bags or folders etc.

It will be understood that I have disclosed the preferred form of my invention as one example only of the many possible ways to practically construct the same and that I may make such changes in the general arrangement and in the construction of the minor details of my invention as come within the scope of the appended claims without departure from the spirit 85 of my invention and the principles involved.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

In a stereoscope, a wire frame open at one end and having its branches angularly bent at this end, a picture holder plate having inwardly rolled flanges to act as guides for picture cards, eyes formed with the inner face of said plate through which the rear bar of said frame is loosely but 86 frictionally guided, and an eye piece holder plate, eyes formed at the inner face of said holder plate for loosely but frictionally guiding the angularly bent ends of said frame to hold the holder plate in position but allowing a folding of the same 0 against said frame beneath the picture holder said lenses.
